Don't Launch Your New Website Until You've Checked These Critical Things

The Details Nobody Tested Are the Ones That Break

Launching a new website is exciting. Your team has obsessed over the design, rewritten the homepage headline more times than anyone wants to admit, and somehow held six meetings about one button.

But here's the uncomfortable truth: the things that actually cause problems after launch are almost never the things you spent all those meetings on. They're the unglamorous details nobody tested. The form that doesn't send. The old page that now returns an error. The image that takes eight seconds to load on a phone.

This post covers the pre-launch checks that get skipped most often, why they cost real money, and exactly what to verify before you hit publish.

The Most Common Failure Is Also the Most Obvious One

Ask any experienced web developer what companies forget before launch and you'll get a surprising answer: contact and lead capture forms don't get tested.

It sounds impossible. Forms are how customers reach you. They're the entire point of the website for most businesses. But forms are usually one of the last things built, and sites regularly go live without anyone confirming they actually work. When that happens, you're not just launching a website with a bug. You're launching a website that silently throws away every lead it generates.

Every form on your site needs to pass three tests before launch:

• It sends. The submission actually arrives in the inbox or system it's supposed to reach.
• The right people get notified. A lead sitting in an inbox nobody checks is the same as a lead that never arrived.
• It's connected to your analytics. If forms aren't hooked into a tool like Google Tag Manager, you have no conversion data. When leadership asks how many leads came in last month, "no idea" is not an answer you want to give.

And test every form on multiple browsers and devices. A form that works perfectly on the laptop it was built on can quietly fail on a phone, and you won't know why until a customer tells you. Or worse, until they don't.

Real QA Means Testing Beyond Your Own Laptop

Quality assurance is the step where you verify the site works everywhere, not just in the environment it was designed in. Most teams skip real QA because it's tedious. That's exactly why it matters.

Your website will render differently across Chrome, Safari, Firefox, Edge, and browsers you haven't personally opened in years. Styles shift. Layouts break. Buttons stop responding. A meaningful slice of your audience is browsing on older devices and less common browsers, and they'll never email you to explain why they left.

The same goes for hardware. Test on a Mac, a Windows machine, an iPhone, an Android, and an older desktop if you can get your hands on one. Nobody enjoys clicking through every page and every form dozens of times. But the alternative is that a real prospect hits the broken version, can't submit the form, and moves on to a competitor. You lose the lead and you never find out it happened.

Redirects Are Where Launches Quietly Bleed Traffic

If untested forms are the most common mistake, broken redirects are the most expensive one. This is the classic "everything looked fine until we launched" scenario. The new site goes live, and by the next morning the emails start: this link doesn't work, that link doesn't work, what happened to the page I bookmarked.

Here's what's actually happening. Your old website earned things over the years: search rankings, backlinks from other sites, bookmarks, links in emails and documents. When you launch a new site with new URLs and don't set up 301 redirects, all of that equity points at pages that no longer exist. The traffic and authority those pages earned doesn't transfer to your new site. It just evaporates.

Two categories of pages absolutely must be redirected:

• Every page with a backlink. If another website links to one of your pages, that link is sending you traffic and authority. Break it and you lose both.
• Every page that received traffic in the past year. Your analytics will give you this list in minutes. It's your shortlist of pages people actually use.

One more rule: redirect to the most relevant page, not the homepage. If someone clicks a link expecting your blue widgets page and lands on your homepage instead, you've broken their journey. They weren't looking for your company in general. They were looking for blue widgets. Send them to the closest matching page every time.

The 30-Minute Version

Sometimes launch day arrives and there's no time for a full review. If you only have 30 minutes, spend them on redirects.

Go to Google and search site:yourdomain.com. That shows you every page Google has indexed, which means every page that's currently capable of ranking and driving organic traffic. Walk that list and confirm each page either exists on the new site or redirects to a relevant replacement. These pages are your organic visibility. Protecting them is the single highest-value thing you can do in a time crunch.

It won't catch everything. But it protects the asset that took the longest to build and would take the longest to rebuild.

The Full Pre-Launch Checklist

With more than 30 minutes, here's the complete list worth working through before any site goes live:

• Test every form across browsers and devices, confirm delivery, notifications, and analytics tracking.
• Set up 301 redirects for every page with a backlink and every page with traffic, pointed at relevant pages.
• Optimize your images. One oversized six-megabyte image can wreck page speed, and slow pages lose visitors before they ever see your offer.
• Rate limit your APIs. If your site connects to paid software services, unprotected APIs can be abused. Companies have woken up to five-figure surprise bills because nobody set a limit.
• Back up your database and confirm you can actually restore it. A backup you've never tested is a theory, not a safety net.
• Check your open graph images. These are the preview thumbnails that appear when someone shares your pages on social platforms. If they're missing or wrong, every share of your content looks broken or confusing.

None of these are complicated. All of them get skipped, because they're invisible when they work and expensive when they don't.

Get the Pre-Launch Worksheet

To make this easier, we turned this entire process into a worksheet you can hand to your team before any launch. It walks through every check in this post, in order, with room to mark off what's been verified and by whom. No guessing, no relying on memory on launch day.

You can grab the Master Pre-Launch Checklist here.

Print it, share it with your developer or agency, and don't sign off on a launch until every line is checked. It's a simple document, but it's the difference between launching with confidence and launching with your fingers crossed.

A Website Launch Should Protect What You've Already Built

A redesign is supposed to move your business forward. But a launch that breaks forms, drops redirects, and slows the site down doesn't just fail to move you forward. It hands back ground you already won: rankings you earned, links you attracted, and leads that were ready to reach out.

The fix isn't complicated. It's discipline. Test the forms. Map the redirects. Check the site everywhere your customers actually are, not just where your team works. The companies that treat launch day as a checklist, not a celebration, are the ones whose new websites start paying for themselves immediately.

If you're planning a redesign and want a partner who treats your traffic, leads, and rankings as assets to protect, we should talk.
